Hi Habib,

I don't think so. First of all, previous fields like cybernetics did  
not die out, but evolved. So now people who studied (or still study)  
cybernetics per se, find their way.

But more importantly, I think that CAS are different from  
cybernetics, chaos, etc. They have lots of potential, and they have  
proven to be useful in lots of areas.
Moreover, there are several funding opportunities focussing on CAS  
(at least in Europe), so if there's funding calling for CAS research,  
people will follow.

CAS also suggest a different way of thinking about the world, but  
wether this will replace Newtonian paradigms in mainstream science or  
not, remains to be seen.

Well, indeed there is yet no "science of complexity", but wether we  
will reach that, or change our concept of science, I think that  
understanding of CAS has been increasing steadily, so I don't see it  
dying out, at least for the next decade. If then we won't be speaking  
about CAS, it won't be because we've forgotten about them, but  
because we've found something better, and in any case CAS knowledge  
will be useful there.

It depends on your purposes.
If describing neuronal bursts as emergent properties increases your  
understanding of the brain, then it's useful. If not, not...
